Here the two samples should be comparable .
The total number of cows in the farm = 200
the total number of cows giving milk = 150
the total number of cows in corral = 20
Suppose total number of cows giving milk in corral = x
The ratio of the total number of cows present to the total number of cows giving milk should be same in farm and corral
so : 200 = 20
------- -------
150 x
now we do cross multiplication :
200 x = 150* 20
200x = 3000
x= 3000/200
x= 15
SO we expect 15 cows in corral should be giving milk .
Answer : 15
Answer:
4.58 * 10 cms.
Step-by-step explanation:
The general form for scientific notation is
N * 10^n (where 1 ≤ N < 10 and n = an integer).
45.8 = 4.58 * 10^1 or 4.58 * 10.
74/258 = %/100 , cross multiply 74 times 100 then divide by 258 = 28.6821705 , rounding it gets you to 28.7%. The answer is D.
Answer:
0.8
Step-by-step explanation:
5 is divided by 5 to get to 1. Divide 4 by 5 to get 0.8.
In a ratio, whatever you do to one side you have to do to the others.
